New Zealand is ideally situated
to generate significant amounts of electricity
from the wind. Our location directly across the
path of the prevailing westerly winds provides
an excellent wind resource.
There are several regions with an
average wind speed above 10 m/s at wind turbine
hub height. This map shows wind resources over
the entire country – mean annual wind speed is
shown at a height of 10m above ground level (representing
surface winds).
